Uwe Marschner,Roland Werthschützkyed viscoelastic materials, when put into operation (fresh concrete, soil, asphalt mixes, filling mastics, mortar with additives, bitumens), can be characterized by a relevant dynamic response that corresponds to a certain type of rheological model. It was found that the product family behaves differ

Uwe Marschner,Roland Werthschützkynsuring stability is done by determining the so-called stability coefficient, in two extreme cases of possible departures from stability, respectively with load and without load. Static stability is a necessary condition for the stability of the crane, but not sufficient. Due to the dynamic demands,

For a beam with random generated crack, the effect of cracking on the change of resonance frequencies was shown by analyzing resonance curves comparing to the health beam. For the four basic resonance frequencies, frequ
